COMBINATION-TOOL.

SPECIFICATION formingpart of Letters Patent No. 423,513, dated March 18,1890.

' Application filed April 29, 1889. Serial No. 309,108. I (No model.)

' f To all whom it may concern-.-

Be it known that we, ALEXANDER CLARKE and J QHN F. CLARKE, subjects ofthe Queen exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

Our invention has for its object to provide a novel combination-tool, tobe used in any ordinary bit-stock, the combined tool having a variety ofuseful tools, such as are more ordinarily in demand, in connectiontherewith,

while, also, any other desired tool of the same general class can bereadily engaged therewith, as may be required.

3 vertical section through the jaws, showing one of the jaws inelevation, with catch in position. Fig. 3 is a similar section showingthe other jaw and certain of the various tools in engagement therewith,with catch removed. Fig. 4 is a top plan. Fig. 5 is a separate view ofthe spring, and Fig. 6 shows a detail view of the shank of a separabletool to be engaged in the jaws of the combined tool.

For many purposes-as, for instance, in carriage-making, for domesticuses, for farmers, and the like-where a kit of tools is not desired orwhere tools are needed in most convenient form, a combination-tool ofthe description herein set forth and illustrated will be found tofacilitate labor, economize time, and embody in itself a cheap devicecapable of a great variety of services.

WVe carry out our invention as follows:

A and A represent jaws constituting the body of our improved tool. Asshown, said body may consist of two jaws properly united in any desiredmanner. In the drawings they are shown connected by a rivet 00. Thesejaws may be cast, and may be, preferably, tapering toward the base,where they are engaged by a ferrule B, preferably milled on itsexterior. Sleeved through said ferrule is a shank O, constructed at oneextremity to be engaged in any ordinary bit-stock. At the opp'osite endthe shank has a screw-threaded engagement with the jaws.

We do not limit ourselves exclusively to the definite construction ofjaws illustrated herewith, nor to any definite manner of engaging theshank O therewith. When the shank is engaged in'a bit-stock, one handmay grasp the ferrule B to steady the tool and keep it in place. Thejaws are recessed at their upper ends, as shown at a a a a to receive aseries of tools, which may be pivotally engaged or otherwise jointedlyunited with the jaws. -'lhus, for example, D is a screw-driver; D, agimlet; D and D diiferent styles of reamers.

We do not limit ourselves to any specific kind of tools to be unitedwith the-jaws nor to anyparticular number of them. WVe have shown fourin the accompanying drawings,

vmay be turned down alongside thejaws, as

shown, out of the way, in which position they may be held securely inany desired manneras, for instance, by afriction-post cZ*-or thefrictional contact of the shoulders cl of the .tools in the recesses a aa a respectively,

may serve to hold the tools in place alongside. the jaws. Any desiredmeans for so holding the tools in place when not in use may be employed.To effect the-entrance of the pivots d, the jaws may be hollowed outadjacent thereto, as shown at a. We do not limit ourselves to the pivotsfor uniting the individual tools in the jaws.

Where it is desirable to facilitate the removal of a given tool from thejaws, a spring stud (1 might be employed. As shown, the end of the studis secured to a short flat the operator, by pressing upon which the toolthem in a firm position.

spring, the latter held normally in close prox-- imity to the surface ofthe jaw by a rivet or bolt, which secures it thereto, the end to whichthe stud is attached having a yielding movement away from the surface torelease the stud from the tool. As so hung or engaged in the jaws it isevident that any given tool of the series may be erected in position foruse, as shown, for example, in. Fig. 1. Being provided with the shoulderd, through which the tools are pivoted to the jaws at one side .of thecenter of the united jaws, it is evident that the tools when erected foruse will be thrown to the center of the jaws.

To hold the tools in an erect position, we

provide a spring-latch E, having a jointed or other proper union withthe jaws, constructed to engage the shoulders of the tools and hold Thusthe latch may be constructed with a notched head 6 and an arm e,extended through one of the jaws, within easy reach of the thumb orfinger of may be released and turned out of the way, a spring (2restoring the latch to its normal position. The individual tools may beconstructed with shoulders d, notched as at d, to

engage the latch, a single latch serving to hold all the toolssuccessively in an erect position. Should it be desired to use aseparable tool with the jaws, a tool F, Fig. 6, for any purpose, itsshank may be formed to enter the open end of the jaws, as shown in Fig.4, for instance, and engage the spring-latch E.

What we claim is' 1. A combination-tool having a body portion providedwith a central opening in one end,and with radial slots or openingsextending from the central opening through to the outside of the tool,tools hinged in the radial slots, and a central catch adapted toautomatically engage any one of the. tools when.- for use, subswung intoextended position stantially as set forth.

2. A combination-tool having abody portion provided with openings in itsend, tools hinged in the openings, a ferrule loosely se cured on theshank end of the body portion for holding the tool, and a catch adaptedto engage the tools and lock them in working adjustment, substantiallyas set forth.

3. A combination-tool. having a body portion'provided with a centralopening in one end, and with slots or openings extending radially fromthe central opening through to the outside of the body, tools hinged inthe said slots, the hinged ends of the tools forming, when the tools arefolded, the walls of an opening to receive a separable tool, and a catchfor engaging the tools, substantially as set forth.

4. A combination-tool comprising a body" portion formed of united jawsor sections, and provided with a central opening and slots radiatingfrom one end thereof, a shank engaged with the body, and aseries'oftools having a jointed engagement with said body, substantially as setforth.

In testimony whereof we sign this specification in the presence of twowitnesses.
